The protecting hood is mainly made from the following components by weight portion: 27 to 67 portions of unsaturated polyester resin, 18 to 28 portions of reinforcing material, 10 to 20 portions of fire retarding agent, 6 to 12 portions of solidifying agent, 1 to 2 portions of toughening agent, 1 to 2 portions of accelerating agent and 1 to 2 portions of brightening agent, wherein the unsaturated polyester resin is selected from 3301, 196, 197 or 198 unsaturated polyester resin, the reinforcing material is selected from glass felt and glass fiber cloth, the fire retarding agent is selected from FR-MP melamine phosphate and FR-CH polyphosphoric acid amide, the toughening agent is selected from dibutyl phthalate and trioctyl phosphate, the brightening agent is selected from diamino stilbene disulfonic acid and phenyl isocyanate, the solidifying agent is selected from hexanaphthene acid peroxide and methyl ethyl ketone peroxide, and the accelerating agent is selected from cobalt naphthenate. The present invention has the advantages of simple installation, simple repair, corrosion prevention, fire retardation, bending resistance and good pressure resistant property.
Description
Technical field
The invention belongs to fluid line appurtenance technical field, the particularly a kind of insulation of fluid line valve, corrosion-resistant safety cover of being used for.
Background technique
At petrochemical industry, coal separation, coal washing industry, the thermal insulating material of various valves all is glass wool, alumina silicate, rock wool and so on.When being incubated installation, at first need valve surface is arrived in these material pavings, also fixed at the outside of thermal insulating material covering one deck aluminium foil or iron sheet then.This heat insulation protecting way construction is complicated, the repair and replacement trouble.Though can play the certain protection effect to valve, elbow, anticorrosion, flame retardant property is poor, iron sheet, the aluminium foil that is covered in the thermal insulating material outside is subject to corrosion such as atmosphere, rainwater and damages, and needs often replacing, not only polluted easily but also influences production.
Summary of the invention
The object of the invention is to provide a kind of installation, maintenance simple valve protective cap; Its further purpose is to provide a kind of anticorrosion, fire-retardant barrier performance good valve protective cap.
For reaching above-mentioned purpose, the present invention adopts following technological scheme: valve protective cap, constitute by half chamber of two symmetries of mutual fastening, and the two halves cavity edge is provided with the arc gap; Two and half chambeies are yin, yang two valve structures, cloudy lobe both sides axial edge has the L shaped flanging that turns up, sun lobe axial edge has the horizontal flanging that turns up, perpendicular distance equals perpendicular distance between the cloudy lobe two flanging vertical edge inner edges between sun lobe two hemmed edges, and two and half chambeies utilize self elastic properties of materials to be fastened and connected together.
The L shaped flanging outer rim in cloudy lobe bottom is provided with upwards rolls over hook.
Cloudy lobe is provided with link at L shaped flanging of turning up of axial edge and positive lobe at the corresponding position of the horizontal flanging of axial edge.
The two halves cavity wall is covered with adiabator layer.
Mainly make: unsaturated polyester resin 27-67 part, reinforcing material 18-28 part, fire retardant 10-20 part, curing agent 6-12 part by the component of following parts by weight.
Also contain following compositions in weight portion: plasticizer 1-2 part, promoter 1-2 part, whitening agent 1-2 part.
Reinforcing material is selected glass felt and glass cloth for use; Fire retardant is selected FR-MP melamine phosphate or FR-CH polyphosphoric acid amine for use; Plasticizer is selected dibutyl phthalate or trioctyl phosphate for use; Whitening agent is selected diaminobenzil disulfonic acid or isocyanic acid benzene fat for use; Curing agent is selected peroxidating cyclohexylenedinitrilotetraacetic acid or methyl-ethyl ketone peroxide for use; Promoter is selected cobalt naphthenate for use.
The design that safety cover of the present invention adopts half chamber by two symmetries of mutual fastening to constitute; after installing thermal insulating material; the thermal insulating material that only needs two and half chambeies are fastened on the valve gets final product outward; install simple, convenient, fast; compare existing iron sheet, aluminium skin protected-type, installation work-hour can shorten 15 times.Owing to do not stay the slit after installing, foreign material are difficult for invading.During maintenance, only need take off two and half chambeies and get final product, and can not destroy safety cover, and safety cover can use repeatedly.On the two halves cavity edge, reserve the arc gap, be used to be nested with valve port.The connection in two and half chambeies can adopt the negative and positive button to be fastened and connected, and this mode is the most simple; Also can adopt to be provided with and attachment hole is set on flanging, the flanging and connects with screw at half cavity edge; Can also be hinged two and half chambeies on one side, another side is threaded.Can cover adiabator layer in advance at the two halves cavity wall, so just not need elder generation, directly can play effective insulation effect to the protection enclosure of band thermal insulating material of the present invention and valve outward at valve outer wrapping thermal insulating material.Safety cover of the present invention can be made anticorrosion, flexible, flexible with the good resins such as 3301,196,197,198 of antiseptic property; Strengthening agent wherein can be selected glass felt for use or glass felt and glass cloth are used in combination, and the safety cover bulk strength is higher; Add promoter and can significantly accelerate the curing rate of material, shorten the manufacture cycle, boost productivity; Add plasticizer and can effectively improve toughness of material, add whitening agent and can make product pure white as a jade, integral body is more attractive in appearance.
Glass fibre reinforced plastics safety cover of the present invention; disposable aluminium skin, iron sheet goods can have been replaced fully; this safety cover is in light weight, anti-aging, convenient disassembly, fire-retardant, anticorrosion, antiseepage, bending resistance, resistance to compression; not only easy to maintenance; also can use repeatedly; both saving of work and time reduced cost of investment again, was easy to apply.
The present invention improves the preparation process of glass fibre reinforced plastics, increases fire retardant, whitening agent, plasticizer, reduces the use amount of glass fiber cloth, selects for use the glass felt table to stick with paste, and has increased density, the intensity of glass fibre reinforced plastics, and anticorrosion, waterproof, barrier performance are greatly improved.
The examination and test of products of the present invention is shown that its Pasteur's intensity is 15 according to GB/T3854, GB/T1447, GB/T1449, GB/T8924, GB/T3857, tensile strength 84MPa, resistance to flexure 135MPa, oxygen index＜18.In 30% sulfuric acid solution, soak under the normal temperature 1 day, in 5% nitric acid, soak 1 day, in 5% hydrochloric acid, soak 1 day, in 10% sodium hydroxide solution, soak 1 day no abnormal.
